The manufactures part number is S178AVK900V2. This kit comes in the hard carrying case, the fusion splicer, a S326 cleaver, three hole stripper, 900um & 250um removable chucks, fixed fiber clamps, battery & battery charger. I bought the unit new in 2017 from Fiber Instrument Sales. There are 1842 splices on this machine and the electrodes have been changed once.
